What version do I have? [noob]

Hi all, a little help please. I have a 508 sw from 2012.

I have a question that is, what version of gps/radio do I have? I don´t know if it is RT6 or wip+, rneg our rneg2.

Based on the pics below can someone help?

Also, what maps (now i have 2011) can I install? and firmware? Because, bluetooth with the iphone 5S is very bad and i was thinking that with a new upgrade it would help

Thank you very much in advance.
